Sumif on Text Columns

CrisCros23  with DAX measures can be achieved two ways (maybe more I am sure of that)

Measure1 =
CALCULATE (
    SUM ( t1[Balance] ),
    TREATAS ( VALUES ( t1[Conca Loc-Partner] ), t1[Conca Partner-Loc] ), ALL(t1)
)
Measure2 =
CALCULATE (
    SUM ( t1[Balance] ),
    FILTER ( ALL ( t1 ), t1[Conca Partner-Loc] = MAX ( t1[Conca Loc-Partner] ) )
)

with PQ you need to self join the table on t1[Conca Loc-Partner] to t1[Conca Partner-Loc]

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45W8ixJzKlU0lFyTy3KTcwDsQwNDJRidaKRRIILEjPzgLQRVAbGh+k1BonHAgA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [C1 = _t, C2 = _t, Value = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"C1", type text}, {"C2", type text}, {"Value", Int64.Type}}),
    #"Merged Queries" = Table.NestedJoin(#"Changed Type", {"C1"}, #"Changed Type", {"C2"}, "Changed Type", JoinKind.LeftOuter),
    #"Expanded Changed Type" = Table.ExpandTableColumn(#"Merged Queries", "Changed Type", {"Value"}, {"Value.1"})
in
    #"Expanded Changed Type"
